A multichannel ECG monitors all 12 leads but usually records how many leads at one time?

Question

Quizplus · Accepted Answer

A multichannel ECG can monitor all 12 leads, but usually records only three leads at a time. This is because monitoring all 12 leads simultaneously requires more electrodes and cables, making it less practical for routine monitoring. The most common configuration for multichannel ECG monitoring is the 3-lead or 5-lead setup, which records leads I, II, and III, or leads I, II, III, aVR, and aVL.
